How did the villages's Jinchuriki manage to leave the village? Like seriously how'd he leave at all?

Also I'm hoping its just a case of unreliable narrator in that Naruto somehow things he could beat Chuunin which have been active service ninja for two years or more. Yeah I get in Canon he beat Mizuki (because 100 12 year olds would in all likelyhood kill a subpar chuunin no doubt) but yeah... Either I feel he's overestimating himself or you've gone an mary-sued him.

The problem with this story is you over explain stuff. It seems like every time Naruto talks he's giving a lecture

I really like this sasuke as he may have a superiority complex but he's working to fix that, he respects naruto and at this rate might become friends with him. I also can imagine sasuke finding out about itachi's true motives and working to save him maybe even not ditching konoha.

To perform the bunshin no jutsu, is it possible for Naruto to do it perfectly if he used the kage bunshin to create enough clones that they all have an average genin chakra level after his chakra is shared, and use one of his clones to perform the bunshin no jutsu correctly?
